Abstract

A seating device includes a headrest movably connected to a seat body. An adjustment mechanism is provided to adjust the position of the headrest relative to the seat body. An operating unit has a driving member to actuate the adjustment mechanism, and a handle portion bending from the driving member. The driving member is movable between non-operative and operative positions. In the non-operative position, the handle portion abuts against the headrest. In the operative position, the handle portion protrudes outward from the headrest.

First claim

What is claimed is:

1. A seating device comprising:
a seat body;
a headrest movably connected to said seat body;
an adjustment mechanism connected between said seat body and said headrest to adjust a position of said headrest relative to said seat body; and
an operating unit movably mounted to said headrest and having a driving member to actuate said adjustment mechanism and a handle portion, said driving member being movable between a non-operative position and an operative position,
wherein,
when said driving member is in the operative position, said handle portion is spaced away and protrudes from an outer surface of said headrest.

2. The seating device as claimed in claim 1 , wherein said handle portion is a bent portion of the driving member and, when said driving member is in the operative position, said driving member is operative to transmit an actuation movement to said adjustment mechanism.

3. The seating device as claimed in claim 2 , wherein, when said driving member is in the non-operative position, said handle portion abuts against said outer surface of said headrest and said driving member is inoperative to transmit the actuation movement to said adjustment mechanism for actuating said adjustment mechanism.

4. The seating device as claimed in claim 3 , further comprising a resilient member urging said driving member to move to the non-operative position.

5. The seating device as claimed in claim 4 , wherein said adjustment mechanism includes a driven member movably mounted to said headrest, said driving member having an active transmitting part, said driven member having a passive transmitting part that engages said active transmitting part in the operative position and disengages from said active transmitting part in the non-operative position, said driving member being able to transmit the actuation movement to said driven member when said passive transmitting part engages said active transmitting part.

6. The seating device as claimed in claim 5 , wherein one of said driving and driven members has an engaging hole defined therein, the other one of said driving and driven members having an engaging pin inserted into said engaging hole, said active transmitting part being situated at one of said engaging hole and pin, said passive transmitting part being situated at the other one of said engaging hole and pin.

7. The seating device as claimed in claim 6 , wherein said engaging hole is elongated and surrounded by a hole boundary, said engaging pin being slidable within said engaging hole.

8. The seating device as claimed in claim 7 , wherein said driving member has said engaging hole, said driven member having said engaging pin.

9. The seating device as claimed in claim 8 , wherein said handle portion abuts against said outer surface disposed at a top end of said headrest when said driving member is in the non-operative position, and is spaced away from said top end of said headrest to protrude upwardly when said driving member is in the operative position.

10. The seating device as claimed in claim 9 , wherein said engaging hole is elongated in a top-bottom direction of said headrest, said active transmitting part being situated at a bottom side of said hole boundary of said engaging hole.

11. The seating device as claimed in claim 10 , wherein said resilient member is configured to normally apply a downward urging force to said driving member.

12. The seating device as claimed in claim 4 , wherein said resilient member connects between said driving member and said headrest.

13. The seating device as claimed in claim 12 , wherein said driving member has an engaging hole defined therein, said resilient member having an end extending into said engaging hole so as to be attached to said driving member.

14. The seating device as claimed in claim 9 , wherein said headrest further has a guide member having a guide groove extending in a top-bottom direction, said driving member slidably extending downward through said guide groove from said handle portion.

15. The seating device as claimed in claim 5 , wherein said adjustment mechanism further includes
a first locking unit mounted to said seat body, and
a second locking unit connected to said driven member and interlockable with said first locking unit to lock said headrest against movement relative to said seat body, said second locking unit being uninterlocked with said first locking unit to allow movements of said headrest relative to said seat body when said driving member actuates said driven member.

16. A seating device comprising:
a seat body;
a headrest movably connected to said seat body;
an adjustment mechanism connected between said seat body and said headrest to adjust a position of said headrest relative to said seat body; and
an operating unit movably mounted to said headrest and having a driving member to actuate said adjustment mechanism and a handle portion bending from said driving member, said driving member being movable between a non-operative position and an operative position,
wherein
the handle portion is configured to
move upwardly away from an outer surface of said headrest to move the driving member to the operative position, and
move downwardly to abut against said outer surface of said headrest to move the driving member to the non-operative position.

17. The seating device as claimed in claim 16 , wherein
when said driving member is in the operative position, the driving member is operative to transmit an actuation movement of the handle portion to said adjustment mechanism, and
when said driving member is in the non-operative position, the driving member is inoperative to transmit the actuation movement of the handle portion to said adjustment mechanism.

18. The seating device as claimed in claim 17 , wherein said adjustment mechanism includes a driven member movably mounted to said headrest, said driving member having an active transmitting part, said driven member having a passive transmitting part that engages said active transmitting part in the operative position and disengages from said active transmitting part in the non-operative position, said driving member being able to transmit the actuation movement to said driven member when said passive transmitting part engages said active transmitting part.

19. The seating device as claimed in claim 16 , further comprising a resilient member connecting between said driving member and said headrest.

20. The seating device as claimed in claim 18 , wherein
the handle portion is configured to automatically move downwardly to abut against said outer surface of said headrest due to a downward urging force of the resilient member.
